QuickApp - P1 Monitor power consumption ⚡️

[SmartHomeEddy 884]

This Quickapp retrieves energy consumption, energy production, gas and water usage from the (P1 Monitor) energy, gas and water meter. 
This Quickapp uses the software of ztatz.nl to get the values from your smart energymeter. 
The ztatz plug-and-play software can run on a Raspberry Pi or in a Docker container. 

 

The Energy consumption and energy production are added to the HC3 energy panel. 
Use the child devices Todays Consumption and Todays Production to store energy data (kWh) in the Energy Panel. 
And use the child devices Consumption and Production for instantaneous power (Watt) in the Energy Panel calculations.

Interval: 
It is possible to process messages from the smart meter every second. Of course, this is only possible if the smart meter actually sends a message every second. This can be turned on via the ztatz software P1 port configuration page via the "maximum processing speed" option. Note that this gives a higher load on the Rpi (or Docker). It has been tested on the Rpi3/Rpi4 and works well on it. Older or other RPIs have not been tested.

The P1 Monitor QuickApp uses 2 API calls each cycle, and if you also use Waterflow, 3 API calls each cycle. With an interval setting of 10 seconds there is an API call every 5 seconds (and with Waterflow enabled, every 3.33 seconds). So the fastest interval setting will probably be 3 seconds with Waterflow and 2 seconds without Waterflow.

No problems, here

Thanks for the good work. ??

Hey guys, i'd like to know. How does the gas flow perform from the p1 port.

 

I use a rooted toon, but it seems the data for gas flow seems to stall or is

sometimes about up to 1 hour slow in updating.  So kind off useless.

[SmartHomeEddy 884]

Although it depends on how Toon calculates the gas usage (the P1 Monitor uses the ztatz.nl software) the Gasmeter sends once every 5 minutes up to once an hour. That depends on your Smartmeter and Gasmeter.

Aha, oke. The strange thing is that sometimes Toon gives almost directly the

correct number. And your Toon quicapp picks that up instantly. But sometimes,

it takes almost an hour to refresh the data from the gasmeter. 

 

So it looks like the CV burner is constant working, but it isnt

[SmartHomeEddy 884]

The communications between the Gasmeter and the Smartmeter isn't reliable in case of the interval. It is reliable for the amount of gas.

 

I also tried with the P1 Monitor to get the actual gas usage at this moment, but that wasn't possible. 

 

 

 

However, there is a solution for you, get a CV burner on electricity (just kidding)

Gas is updated every time there is a read out.

Well, I had to make a choice. Either charge the 3 teslas or get off the gas. I chose a Renault.

Not sure if "every time there is a read out" is fast enought for my likings.

 

But then again, i just might need to try that ztatz software soon, just to see

how it performs compared to the Toon/p1 readout.

The P1 monitor reads out every second, but the Smartmeter isn’t updated from the Gasmeter with that read out.

You're correct.

Did a stopwatch metering. Looks like the electricity is updated every 10 seconds, and the gas boiler ever 5 min. (made sure the boiler was on)

This was just a short try for fun. no scientific set-up. ?

Did the test for approx. 30 minutes. Now its very hot in the bathroom. ?

I am working on an update of the P1 Monitor quickapp. 

 

The new version includes translations for different languages. If you want your language included, please let me know. 

[SmartHomeEddy 884]

A new version of the P1 Monitor quickapp is available.

• Removed Power device calculation
• Removed child devices for gross consumption and device consumption
• Changed code to multi file
• Added for translations for English, French, Polish and Dutch

 

The child devices changed, so you need to replace your current quickapp with a new one.

(And after install, don't forget your Energy panel setup of the child devices)

Hi

@SmartHomeEddy

It's a very good QA, thanks !

 

But there is a strange situation that I don't understand. On the energy panel, for consumption, the total is not real because it is very different from reality.
When I turn on the electric oven which consumes 2000w, the display suddenly rises to more than 6000 w
I attach 3 screenshots, 1 of the measurement with the E4U module from Noks, 1 of the P1 monitor app, and 1 of the P1 with Yubii (your QA)
The info in on PC with Home Center of the HC3 is correct and corresponds to reality.
Any idea on the reason for this big difference?

 

E4U (Noks) :

Home Center HC3 (on PC) :

 

Your QA with Yubii app :

[JLT007 3]

Hi,

now with the new version of yubii 1.18.1, the current power data displayed is correct and same as P1 monitor app and E4U. So, I suppose, the problem was with the old yubii app

[SmartHomeEddy 884]

Could be the Yubii app.
 

But it could also be the settings of the “Use instantaneous power in Energy Panel calculations”. All devices with the power (Watt not kWh) option have this setting.

 

It is important to check all your power devices for this setting. The power (Watt) consumption can be measured by more than one device, like a child device of the P1 QuickApp and a wall plug. You should only set ONE “Use instantaneous power in Energy Panel calculations”, otherwise the power (Watt) consumption counts double or even triple. 

[JLT007 3]

Thank you for the details. I didn't change anything in the QA when the display became correct again with the new version of yubii.

So I think the new version of yubii has corrected something at this level
Last year I actually had several items that had the box checked for: "Use instantaneous power in Energy Panel calculations"
And the data was obviously completely wrong!
Since the beginning of this year I fixed this and as you suggested, there is only one QA device (P1 Monitor) which has the box checked.
In this regard, I would have liked to be able to erase the erroneous data for the past year so that the totals are correct, but I have not found a way to do this. An idea ?

Maybe the newer HC3 formware solved your problem.

You can select the device(s) for power consumption and production (Watt). 
 

I haven’t found a way to delete only the power values. You can clear all energy values of devices in the panel settings, but then all energy values will be gone. 
 

 

Edited March 12, 2023 by SmartHomeEddy

[JLT007 3]

Ok, if there is no way to erase just one year, then I leave the file as it is.

I made the selection as shown below, is that correct?

The numbers correspond to the index of the smart meter
181 and 182 for consumption, and 281 and 282 for injection
